Frequent blood glucose measurement is one element of the routine intensive monitoring that all critically ill patients receive following admission to intensive care units. Transient increase in blood glucose concentration (hyperglycemia) is very common in this patient group.  The significance of this so called stress...

Sepsis is a major cause of mortality and morbidity for hospitalized patients around the world. Early intervention can reduce mortality and morbidity from severe sepsis, but signs and symptoms of sepsis are non-specific. Point-of-care lactate has proved to be an invaluable tool for some institutions in standardized...

Patients with sepsis, severe sepsis and/or septic shock are at increased risk of death and organ dysfunction.  While morbidity and mortality of patients with severe traumatic injury, acute myocardial infarction or stroke have been significantly reduced during recent years by the implementation of well-coordinated...

Pulse oximetry provides the means for continuous non-invasive monitoring of blood oxygenation by measuring % oxygen saturation (SpO₂). This safe, easy and convenient method of monitoring oxygenation status is ubiquitous in clinical medicine and is now a routine part of the overall assessment and monitoring of all...

Mechanical ventilation is necessary for survival of patients with acute respiratory distress syndrome (ARDS). It was once supposed that ventilation should be adjusted to maintain pCO₂(a) within the normal range but this degree of mechanical ventilation can result in further damage to the lungs. Less aggressive (low...

Around a third of critically ill patients are given transfusion of packed red cells but there is an ever-growing body of research evidence to suggest that blood transfusion may not be as beneficial to all patients as was once supposed.  Some studies, for example, have revealed that patients given transfusion might be...

As a global marker of tissue oxygenation serum lactate measurement has proven its usefulness in monitoring the critically ill. It has also proved useful as a screening tool for sepsis in the emergency room.  However, lactate measurement is not always readily available. Increased lactate is a common cause of raised...

Timely and accurate diagnosis of sepsis is of great importance for the choice of treatment, level of monitoring and prognosis. For this biomarkers could be a significant aid, and thus the search for and application of sepsis biomarkers are of great importance.  Current evidence suggests that C-reactive protein and...
